A second vote for conduit.
Not much will change in the big scheme of things. HDMI/Display Port are two of the few things that might. That being said, since we installed our conduit during the building process, i can now run Gigabit ethernet cabling if required. I can never remember if i installed Cat5 or Cat5e cabling those 9 years ago. Theoretically i can use the Cat5 but i should probably upgrade it.
I can easily do that with the conduit.
Ahh, good point - conduit between electronics and display would be really useful, even if wires between electronics and speakers are sufficient.
Maybe "conduit between electronics and anything that isn't a speaker" is the correct wording.
